Sophie Tucker (January 13, 1884–February 9, 1966) was a singer and comedian, one of the most popular entertainers in America during the first two-thirds of the 20th century.

She was born Sonia Kalish to a Jewish family in Tsarist Russia. Her family emigrated to the United States when she was an infant, and settled in Hartford, Connecticut. The family changed its name to Abuza, and her parents opened a restaurant.

She started singing for tips in her family's restaurant. In 1903, at the age of 19, she was briefly married to Louis Tuck, from which she decided to change her name to "Tucker". (She would marry twice more in her life, but neither marriage lasted more than five years.)
